Ah ok, that's fair enough. I am coming at this as a programmer, wanting to know if anyone else has edited any of the files I'm working on. But obviously, if it's better elsewhere that's fine by me! Thanks.

make a copy of your local directory, then use rsync to synchronize the local copy with the remote directory and finally, use diff between the original directory and the modified copy to find out the differences.
